Structures, luminescence and photocatalytic properties of two nanostructured cadmium(II) coordination polymers synthesized by sonochemical process

Structures, luminescence and photocatalytic properties of two nanostructured cadmium(II) coordination polymers synthesized by sonochemical process
By varying the dicarboxylate coligands, two nano-sized cadmium(II) coordination polymers (CPs), [Cd(bix)(DCTP)] n (1) and [Cd(bix)2(BPDC)] n (2) (bix=1,4-bis(imidazol-1-ylmethyl)benzene, H2DCTP=2,5-dichloroterephthalic acid, H2BPDC=biphenyl-4,4′-dicarboxylic acid) were synthesized hydrothermally and sonochemical irradiation. CPs 12 and their nanostructures have been characterized by elemental analysis, single-crystal X-ray diffraction, and scanning electron microscopy (SEM). CP 1 features a uninodal 4-connected 2D sql network consisting of two different helical arrays. Whilst, CP 2 displays 2D layer which constructed by the linear chains and M2L2 type discrete loops. The effect of ultrasonic power and temperature on the morphology and size of CPs 12 are investigated in detail. Nano-sized 12 show the relatively high photocatalytic performance for degradation of Methylene Blue (MB) under UV irradiation.
